What Is eJOY English?
eJOY English is a language learning platform built around a Chrome browser extension. It lets you look up English words while watching videos on YouTube, Netflix, and other websites by simply double-clicking on subtitles or any text on a webpage.
Originally launched as a free tool for Vietnamese learners, eJOY English has grown to support multiple languages and millions of users worldwide. Its core idea is simple: learn vocabulary in context by watching real videos, rather than memorizing word lists in isolation.
The platform includes a web dashboard where you can review saved words using flashcards and mini-games. eJOY also offers curated video courses on topics like business English, IELTS prep, and everyday conversation.
eJOY Extension: How It Works
The eJOY Extension is a Chrome browser extension (also available for Edge and Firefox) that overlays on video platforms and websites. Here's how the typical workflow looks:
- Install the extension from the Chrome Web Store
- Open a YouTube or Netflix video with English subtitles
- Double-click any word in the subtitles to see its definition
- Save the word to a personal wordbook for later review
- Review saved words using eJOY's flashcard games on their website
The extension supports dual subtitles — showing both English and your native language simultaneously. This is useful for beginners who need translation support while watching. (For a deeper look at the dual-subtitles approach, see our Language Reactor review, which covers the same workflow in more depth.)
One limitation: because eJOY runs as a browser extension, it only works on desktop browsers. There's no dedicated mobile app or standalone learning interface. Your learning experience depends on the video platform's own UI, which can be cluttered with ads and recommendations.
eJOY AI Dictionary: Is It Worth It?
eJOY introduced an AI dictionary feature that goes beyond traditional dictionary lookups. Instead of showing a generic definition, the AI dictionary attempts to explain what a word means in the specific context of the sentence you're reading.
This is a step in the right direction — context matters enormously when learning vocabulary. The word "bank" means something different in "river bank" vs. "bank account."
However, eJOY's AI dictionary has notable limitations:
- It primarily provides definitions only — no collocations, synonyms, or example sentences
- No phonetic transcription (IPA) is included
- The AI-generated explanations are not always accurate, especially for idiomatic expressions
- It's a premium feature, locked behind eJOY's paid plans
Compare this with TubeVocab's AI flashcards, which generate comprehensive vocabulary cards including contextual meaning, phonetic transcription, collocations, synonyms, antonyms, and multiple example sentences — all from the exact video context.
eJOY English Pricing in 2026
eJOY English uses a freemium model. Here's a breakdown of what you get at each tier:
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | Basic word lookup, limited saves, standard dictionary |
| Pro | ~$4.17/mo (annual) | Unlimited saves, AI dictionary, all review games |
| Lifetime | ~$100 (one-time) | All Pro features, lifetime access |
The free tier is quite limited — you can only save a handful of words per day, and you don't get access to the AI dictionary. For serious learners, the Pro plan is essentially required. In comparison, TubeVocab's pricing offers a generous free tier with AI-powered flashcards included from day one.
